Butterfly Wing Design Helps Increase Solar Output by 50%

A new research reveals that the butterfly wing design may be an indicator for module manufacutrers to create cheaper and more efficient solar panels. The Cabbage White butterfly folds its wings in a v-shape to heat up their flight muscles before launching into the air. Scientists at the University of Exeter found that by replicating this posture with solar panels, they could increase solar output by nearly 50%.

Butterflies’ ability to fly on cloudy days is limited by the energy the insects can get from the sun. But the Cabbage White butterfly is able to take off sooner than other types of butterflies even on cloudy days. Researchers discovered this is because the Cabbage White positions its wings in order to concentrate sunlight onto its thorax and speed up the “charging” process.

Taking a cue from this information, the researchers were able to create a new, lightweight material that can be positioned in a v-shape to concentrate sunlight on solar panels. And in so doing, they increased solar output by almost 50%.

This isn’t the first time researchers have turned to nature for inspiration, but this discovery is particularly exciting because of its implications for solar power everywhere. “Biomimicry in engineering is not new. However, this truly multidisciplinary research shows pathways to develop low cost solar power that have not been done before,” said Professor Tapas Mallick, lead author of the research.
